菜鸟入门stm32群主所创关于结构体初始化

1、我们一般见的结构体初始化有两种：cpp HYPERLINK /ieczw/article/details/17074573 o view plain view plain HYPERLINK /ieczw/article/details/17074573 o copy copytypedefstructuint32_tI2C_ClockSpeed;/*!Specifiestheclockfrequency.Thisparametermustbesettoavaluelowerthan400kHz*/uint16_tI2C_Mode;/*!SpecifiestheI2Cmode.Thispara

2、metercanbeavalueofrefI2C_mode*/uint16_tI2C_DutyCycle;/*!SpecifiestheI2Cfastmodedutycycle.ThisparametercanbeavalueofrefI2C_duty_cycle_in_fast_mode*/uint16_tI2C_OwnAddress1;/*!Specifiesthefirstdeviceownaddress.Thisparametercanbea7-bitor10-bitaddress.*/uint16_tI2C_Ack;/*!Enablesordisablestheacknowledge

3、ment.ThisparametercanbeavalueofrefI2C_acknowledgement*/uint16_tI2C_AcknowledgedAddress;/*!Specifiesif7-bitor10-bitaddressisacknowledged.ThisparametercanbeavalueofrefI2C_acknowledged_address*/I2C_InitTypeDef;比如这个结构体，我们一般这样初始化：cpp HYPERLINK /ieczw/article/details/17074573 o view plain view plain HYPER

4、LINK /ieczw/article/details/17074573 o copy copyI2C_InitTypeDefi2c;i2c.I2C_Ack=I2C_Ack_Enable;i2c.I2C_AcknowledgedAddress=I2C_AcknowledgedAddress_7bit;i2c.I2C_ClockSpeed=clock*1000;i2c.I2C_DutyCycle=I2C_DutyCycle_2;i2c.I2C_Mode=I2C_Mode_I2C;i2c.I2C_OwnAddress1=addr;cpp HYPERLINK /ieczw/article/detai

5、ls/17074573 o view plain view plain HYPERLINK /ieczw/article/details/17074573 o copy copyI2C_InitTypeDefi2c=I2C_Ack_Enable,I2C_AcknowledgedAddress_7bit,clock*1000,I2C_DutyCycle_2,I2C_Mode_I2C,addr;希望大家不要纠结我这个结构体变量的顺序，肯定错了，我只是说下有这种方法！但是在linux内核里面有这样一种初始化方法：cpp HYPERLINK /ieczw/article/details/17074573 o view plain view plain HYPERLINK /ieczw/article/details/17074573 o copy copyI2C_InitTypeDefi2c=.I2C_Ack=I2C_Ack_Enable,.I2C_AcknowledgedAddress=I2C_AcknowledgedAddress_7bit,.I2C_ClockSpeed=40000,.I2C_DutyCycle=I2C_DutyCycle_2,.I2C_Mode=I2C_Mode_I2C,.I2C_OwnAddress1=0 x0a;但是在keil里面默认是不可以用这种
